PIN-HOLE-PERFORATING MACHINE.

SPECIFICATION forming part of Letters Patent No. 364,248, dated June 7, 1887. 4

Application filed Februar-5 28, 1887. Serial No. 229,172. (No model l To all whom it may concern,.-

Be it known that l, HANs C. HANSEN, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Pin-HolePerforating Machines, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to improvements in pin-hole-perforatin g machines for the purpose of perforating sheets of paper, card-board,&c., and it is carried ont as follows, reference being had to the accompanying drawings, where- Figure l represents a centrallongitudinal section of the improved machine. Figs. 2 and 3 represent, in detail and full size, respectively, end and side views of the perforating device.

Similar letters refer to similar parts wherever they occur on the drawings.

this kind.

bis the drivingshaft, located in bearings a", a3 and a4 in the goose-neck a', as shown in Fig. 1, and to the forward end of said shaft is secured, by means of the nut b', the punchwheel C, provided with the radial punches c c, as shown.

b is a collar on shaft b, at the rear of gooseneck bearing a4, to prevent a longitudinal movement of said shaft in its bearings. To the rear end of shaft b is secured the fast pulley b, to which a rotary motion is conveyed by means of a belt, as usual.

b4 is the loose pulley, located on shaft I, between the fast pulley b3 and the rear gooseneck bearing e, as shown in Fig. l.

D is the work-supporting table. (Shown in Figs. l and 2.)

Below the rotary punch-wheel C is located, on shaft c, the die-wheel E, having radial perforations e e through its flanged periphery, corresponding in size and number to the radial punches c c on the rotary punch-wheel O, as is common on machines of this kind. The die-wheel shaft c is supported in bearings ff, cast in one piece with the base-platef, which latter is secured to frame a by means of setscrew ff and bridge-plate f, (shown in Fig. 1,) or equivalent or well-known devices.

Outside of the bearings f f for the die-wheel shaft e are secured to the latter the feed or guide wheels G G, having peripheral grooves ,(1, (shown in lowerright-hand portion of Fig. 3,) in which are laid the annular rubber bands g g, as shown, to produce a proper friction in connection with other devices, hereinafter to be described, forfeeding and guiding the material to be perforated.

A positive rotary motion is imparted to the die-wheel E and guide or feed wheels G G from the punclrwheel C by the radial punches c c entering the radial perforations in t-he diewheel E, as shown in Fig. l. The die-wheel shaft c' is free to adjust itself longitudinally in its bearings ff, so as to compensate for any inequalities in the positions of the punches c c relative to the perforations e e in the diewheel, andior this purpose each bearing f is made a little narrower than the distance between the hub of the die-wheel E and inside of the respective feed and guide wheels G G, as shown in Figs. 1 and 3. To the goose-neck bearing a4 is secured, by means of ears h h and screws h zf, the curved metal plate H, as shown, said plate having a slot, h, (shown in Fig. 1,) through which passes a portion of the puncl1- wheel C, which plate serves for the purpose of disengaging the perforated paper from the punches c c, and preventing it from being carried around the said `punch-wheel. In slots H H in the ends of said plate H are loosely journaled the reduced portions lo k of the auX- iliary feed and guide rollers KK, as shown in Figs. 2 and 3, and each `opposite pair of such rollers is provided with an elastic endless band, 7c', that lies in contact with the friction-band g on its corresponding roller or guide-wheel G, as shown in Figs. 2 and 3.

I make on opposite of the curved plate H a pair of inverted 1-shaped guides, hah, directly above the respective yfeed or guide wheels G G, as sho-wn in the drawings, for the purpose of properly guiding the elastic bands 7c It to and from their respective rollers K K, and thus preventing said bands from running ofi" said rollers.

As the guide and feed wheels G G are rotated, their friction-bands g g impart a continuous rotary motion to the rollers K K and their frction-bands k la.

IOO

If the paper to be perforated is of sufficient width, it is introduced between both the roll-- ers or guide-wheels G G and the endless ear- 1ying-bands7c7s, and the punch and die wheels t)C E arranged between them, by which the paper to be perforated is properly fed and guided, and prevented from being carried to the right-or left of a true linear motion.

If the paper to beA perforated is not wide enough to be carried by both the wheels G G, either one of them, in connection with the corresponding ends of rollers K K and one of the bands k, will serve the purpose of properly guiding the paper as it is being fed forward by the punch and die wheels G and E.

The operation of the machine is as follows: The shaft b and punch-wheel C is set in a rotary motion by the means described, causing the die-wheei E and guide-wheels G G to be correspondingly rotated positively and with equal velocity, and motion imparted to the bands k k by the wheels G G and their bands g g. The paper is then fed onward on the table D, and introduced between the wheels G G and the endless carriers or bands 7c' k', causing the paper to be fed and guided to the punch and die wheels C E, where the puueh ing takes place, after which the now finished paper is disengaged from the punches c c by being carried below the curved plate H. By this construction and arrangement of parts as described the paper to be perforated is most positively fed and guided to and from the perforating devices without any liability of being carried to the right or left of the central line in which the perforations are to be made, and by these means I am able to produce most accurate work.

Having thus fully described the nature, con struction, and operation of my invention, I wish to secure by Letters Patent, and claim- 1. In a perforatingmachine, the rotary punch-wheel C, having radial punches c c, in combination with the die-wheel E and guidewheels G G, secured to the longitudinally-ad justahle shaft e', and having the annular friction-bands g g', and the loosely-rotating rollers K K, having the endless bands 7c' k', as and for the purpose set forth.

2. The diewheel E and guidewheels G G, secured to the shaft e', in combination with the stationary plate H, its rollers K K, endless bands lc la', and inverted I I-Shaped bandguides h3, as and for the purpose set forthB In testimony whereof I have signed my name to this speeitieation, in the presence of two subscribing witnesses, on this 25th day of February, A. D. 1887.
